RAILVIAY TIE AND SECURING DEVICE.

To all whom it may concern.

Be it known that, I, SAMUEL \VALLWORK, a citizen of the United States, and a resident of Summerville, in the countyof Jefierson and State of Pennsylvania, have made a new and useful Invention in Railway Ties and Securing Devices, of which the following is a specification.

-he invention relates to metallic railway ties and more particularly to the fastening means for clamping the rails to the ties. It. is designed for use'in mine work butis not limited to use in such connection. lit has for its principal objects; the provision of a tie and securing device of cheap, simple construction in which the clamping means can be very easily applied and released or tightened in service, and in which the clamping effect is very secure and not liable to work loose. Certain embodiments of the invention are illustrated in the accompanying drawings wherein;

Figure 1 is a plan view showing one form of construction; Fig. 2 is an enlarged section on the line IT-II of Fig. 1; 3 is a plan view illustrating a modification; Fig. 4 is a plan view of another modification involving the preferred form of construction; and Fig. 5 is a section on an enlarged scale onthe line V-V of Fig. 4.

Referring to the construction shown in Fig. 1, the numeral 1 designates a metal tie preferably in the form of a commercial i channel with its flanges turned down and carrying at its ends the rails 2, 2 of the usual cross section. The flanges of the channel are cut adjacent the ends thereof, and such flanges and the web therebetween are turned up to form the hooks 3, 3 which it around the outer flanges of the rails and fix the gauge, and hold the rails against out-ward parts on the other side of the rail.

movement.

The inner sides of the rails are held by the clamping plates 4. 4, which are similar, so the description will be directed to one only. The plate 4 is provided with a cam slot 5 which extends over a perforation in the tie (Fig. 2) and receives the clamping bolt 6. The upper end of the bolt carries the nut 7, and to increase the bearing on the plate, the washer 8 is employed. The upper end of the bolt is preferably riveted over as indicated at 9 (Fig. 2) to maintain the nut in the position to which it is adjusted.

To apply the plate, the nut is adjusted so that the inner edge of the plate or one cor- Specification 0)": Letters Patent.

ner thereof (which may be slightly thinned driven endwise in the direction of the arrow by means of a sledge,the bolt, co-operating with the cam slot, camming the plate inward over the rail flange until sufficient overlap and aproper tension are secured in the plate. This will ordinarily occur before the inner edge of the plate engages the web of the rail, and at this time the plate will be slightly bent as indicated in Fig. 2 so that a yielding spring tension is applied to the rail flange. This gives a very secure holding of the rail even though the plate (which is ordinary steel plate) receives a partial set in. the course of time. In case the grip of j the plate loosens, it canbe readily tightened by adjusting down the nut 7.

bolt 6, thus bringing the edge 10 over the flange of the rail.

Fig. 3 illustrates a modification in which the inner clamping plate 4 and its associate parts are similar to those heretofore described'in connection with Figs. 1 and 2, but the tie 11 isextended under the rail as indicated at 12, and a similar clamping plate 13 is applied on the outer side of the rail.

This plate is provided witha cam slot 14 and bolt 15 similar to the corresponding Fig. 4 illustrates a further modification in which the rail 2 is clamped by two plates 16 and 17 held by the single bolt 18. The plate 17 lies beneath the other plate and has its outer portion extended beneath the rail and provided with a hook portion 19 engaging the outer flange of the rail. The upper plate 16 is provided with a cam slot 20, and this plate and its co-operating bolt correspond throughout with the construction of Figs. 1 and 2, the bolt having a nut 21 and the plate being sprung as shown in driving it to position. The lower plate 17 has a slot 22 similar to the slot 20 but at the reverse angle so that both plates may be driven in the same direction in order to tighten them by the same series of blows. In loosening, both plates are driven in the reverse direction.

It will be observed that the material used in all of the forms of construction consists of commercial sections and plates requiring little machine work and no special castings so that the construction can be very cheaply fabricated. Also that the device is particularly adapted to mine work where much shifting and relaying of tracks and switches are required, since the clamps may be very easily and quickly applied by driving or hammering the parts and with a minimum of labor in screwing and unscrewing of bolts such as is ordinarily required in track work. I have found that commercial plate as used in the clamp has just the requisite amount of spring and give to lend itself to this method of procedure, and that thedegree of security is ample for this class of work.

What I claim is;

1. The combination with a flanged rail and a metal tie having a perforation adjacent the flange of the rail, of a clamping plate of wrought metal having a cam slot over said perforation and lying at an angle to the line ofthe rail with its edge lying over the flange of the rail, and a headed locking member extending through said perforation and slot and clamping the plate so that the plate is sprung or bent and applies yielding pressure to the rail.

2. The combination with a flanged rail and a metal tie having a perforation adjacent the flange of the rail, of a clamping plate of wrought metal having a cam slot over said perforation and lying at an angle to the line of the rail with its edge lying over the flange of the rail, a screw-threaded lockingmember extending through said perforation and slot, and anut on the said member above the plate and positioned so that the plate is clamped against the rail flange with yielding pressure, the end of the member being riveted over to hold the nut in said position.

3. The combination with a flanged rail and a metal tie having a perforation adjacent the flange of the rail, of a clamping plate of wrought metal on the inside of the rail having a cam slot over said perforation and with its inner edge lyingover the flange of the rail, a second clamping plate lying beneath the first clamping plate and also provided with a cam slot lying over said perforation and having its outer portion extended beneath the rail and provided with a hook at its outer end extending around the outer flange of the rail, and a headed locking member extending through said perforation and through the two cam slots.

i. The combination with a flanged rail and a metal .tie having a perforation adjacent the flange of the rail, of a clamping plate of wrought metal on the inside of the rail having a cam slot over said perforation and with its inner edge lying over the flange of the rail, a second clamping plate lying beneath the first clamping plateand also provided with a cam slot lying over said perforation and having its outer portion extended beneath the rail and provided with a hook at its outer end extending around the outer flange of the rail, a threaded locking bolt extending through said perforation and the two cam slots, and a nut 011 the upper end of the bolt placing the inner clamping plate under clamping tension against the flange of the rail.

5. The combination with a flanged rail and a metal tie having a perforation adjacent the flange of the rail, of a clamping plate of wrought metal on the inside of the rail having a cam slot over said perforation and with its-inner edge lying over the flange of the rail, a second clamping plate lying beneath the first clamping plate and also pro vided with a cam slot lying over said perforation at an angle the reverse of that of thefirst clamping plate and having its outer portion extended beneath the rail and provided with a hook at its outer end and extending around the outer flange of the rail, and a headed locking member extending through said perforation and through the two cam slots. i

In testimony whereof, I have hereunto subscribed my name this 13th day of April,

SAMUEL WALLl VORK.
